Spatial dispersion control with Laue-geometry photonic crystals

We propose and experimentally demonstrate an integrated approach to suppress Kerr self-focusing by engineering the spatial dispersion of a medium using photonic crystals of Laue geometry (Laue-type PhC). The PhC, featuring longitudinally chirped and constant-period sections, was designed using a bea...
